终端中的$idl命令不启动IDL

Question

在终端中输入$idl将返回“未找到命令”。

‘well’也没有提供任何东西。

默认IDL_PATH为：

/Applications/exelis/idl83/lib/bridges:/Applications/exelis/idl83/lib/datatypes:/Applications/exelis/idl83/lib/dicomex:/Applications/exelis/idl83/lib/graphics:/Applications/exelis/idl83/lib/hook:/Applications/exelis/idl83/lib/imsl:/Applications/exelis/idl83/lib/itools/components:/Applications/exelis/idl83/lib/itools/framework:/Applications/exelis/idl83/lib/itools/ui_widgets:/Applications/exelis/idl83/lib/itools:/Applications/exelis/idl83/lib/obsolete:/Applications/exelis/idl83/lib/utilities:/Applications/exelis/idl83/lib/wavelet/data:/Applications/exelis/idl83/lib/wavelet/source:/Applications/exelis/idl83/lib:/Applications/exelis/idl83/examples/data:/Applications/exelis/idl83/examples/demo/demodata:/Applications/exelis/idl83/examples/demo/demoslideshows/slideshowsrc:/Applications/exelis/idl83/examples/demo/demosrc:/Applications/exelis/idl83/examples/demo:/Applications/exelis/idl83/examples/doc/bridges:/Applications/exelis/idl83/examples/doc/dicom:/Applications/exelis/idl83/examples/doc/file_io:/Applications/exelis/idl83/examples/doc/image:/Applications/exelis/idl83/examples/doc/itools:/Applications/exelis/idl83/examples/doc/language:/Applications/exelis/idl83/examples/doc/objects:/Applications/exelis/idl83/examples/doc/plot:/Applications/exelis/idl83/examples/doc/sdf:/Applications/exelis/idl83/examples/doc/shaders:/Applications/exelis/idl83/examples/doc/signal:/Applications/exelis/idl83/examples/doc/utilities:/Applications/exelis/idl83/examples/doc/widgets:/Applications/exelis/idl83/examples/HP_TIFF:/Applications/exelis/idl83/examples/imsl:/Applications/exelis/idl83/examples/misc:/Applications/exelis/idl83/examples/mjpeg2000:/Applications/exelis/idl83/examples/ogc/wcs:/Applications/exelis/idl83/examples/ogc/wms:/Applications/exelis/idl83/examples/widgets/wexmast:/Applications/exelis/idl83/examples/widgets:/Applications/exelis/idl83/examples:/Applications/exelis/idl83/idlde/plugins/com.rsi.idldt_8.3.0/icons

为了能够从命令行启动IDL，我在path中添加了一百万次操作，但都不起作用。我被难住了。请帮帮我！

IDL_PATH不是系统路径。将idl添加到系统路径中，例如：

$ export PATH=/Applications/exelis/idl/bin:$PATH
